Open Heart Surgery

I watched an open heart surgery today. Basically, this person would not have made it up to this point (5 days old), before modern technology. I saw a heart taken apart, the top lobe of the right lung moving up and down, the body put on a bypass machine to keep the body alive, and the heart flatlined. This is a gross image, but think cherry slushy...the scrub nurse put crushed ice in the cracked open chest to keep the heart cool. And there was a piece of equiptment that looks like a whisk.
